To all whom it may concern:

Beit known that I, WILLIAM It. MOORE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Engraving- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

rIhis invention relates to improvements in machinery for tracing and engraving letters or designs of various sizes upon metal surfaces by means of a pattern, as a guide, whereby a saving of time and labor, as well as accuracy and uniformity in the character of the work, is accomplished.

The object of the invention is to simplify and improve the construction of this class of machines.

To this end the invention consists in the novel construction and arrangement of parts, as will be hereinalter more fully described, and specifically pointed out in the claims.

In the accompanying drawings, to which reference is had and which fully illustrate my invention, Figure l is a side elevation of the machine embodying my improvements. Fig. 2 is a perspective view of one of the workholders and clamping-bars or follower, and Figs. 3 and 4 are detail views thereof. t.

Similar letters of reference indicate similar parts throughout the several views.

A represents a vertical standard, in this eX- ample made of metal tubing or gaspipe; but, if preferred, it may be made of any suitable material. To the upper and lower ends of this standard A are permanently secured or formed 4integral therewith, at right angles to A, an u pper and lower outer arm, A A2, the upper arm, A', having a perforation in its ends to receive a main adj Listing-screw, for a purpose which will be hereinafter explained. The free end of the lower arm, A2, is secured to a bedpiece, AS, having perforations made in its ends to receive screws a, by which it is secured to a table or other suitable fixture to hold the standard A and its attachments firmly in place.

Near the upper and lower ends of the standard A, and between the outer arms A and A,

are loosely secured, by means of set-screws I) l b, T- shaped adjustable thimbles or sleeves C C, the projecting ends of which receive one end each of two adjustable work-holding hollow arms, D D, the opposite ends of these arms being perforated near their free ends and pro vided with perforated collars E E, the perfora tions in the arms and collars being in alignment with each other, and through which are passed thumb-screws e e, which loosely secure the inner ends each of two shorter and telescopie extension-arms, F F, the outer ends of which are bifurcated and terminate in enlarged or collared ends f f, having perforations f therein, through which are passed screws or pins G G, which loosely secure the downwardly-projecting stems I-I of a pattern and work-holder plates H and holders H2 in the bifurcations in the outer or free ends of the telescopicextension-armsFF. Thumb-screws h h are passed through perforations IL h', made in the collared or enlarged ends of the telescopic arms F, by which is given one of the various adjustments to the pattern and workholders at these points.

The elements just described and designated by the letters A A', A2 A, D D, and F F compose the main frame of the machine.

Pivotally secured to the outer end of the arm A by means of the main adj usting-screw VB and a ball-and-socket joint, I, and clearly shown in Figs. l and 4 of the drawings, is an auxiliary tool carrying operative frame K M N O, composed of a long upper horizontal arm having secured to its free end a counterpoise, L, the opposite end of this arm being secured to or formed integral with the upper end of a vertical arm, to the lo'wer end of which is similarly secured another horizontal arm, the4 outer or free end of which terminates in enlarged or hollow capped end n. Secured to the under side of the arm K, about midway thereof, is the vertical end of a short angular arm, O, the other or free end terminating in a hollow capped or enlarged end, o, similar to the free end of the arm N. Both of these arms-the angular arm O and the horizontal arm N-have their free ends perforated in a vertical direction to receive the passage through them of the tool-stocks P P of the tracing-tool Q and graver Q', said stocks of the respective tools being in alignment with each IOO other. The stocks P and P', or the tool-holders hcreinbefore mentioned, are pivotally secured by stems a at their upper ends, as at p, to the free ends of a crane or bracing, It, the opposite ends of said bracing overlapping each other and terminating in a V-shaped point, which is pivoted together, as at R, and to the rear and free end of a projected short arm, S, of the vertical arm M. Near the' point where the crane orbraci ng begins to assume a V shape a vertical bar, T, is pivoted at each end, as at t, said bar serving to further re-enforce and strengthen the crane or bracing R, l'rom the free ends ot' which the tool-holders or stocks P P' depend. Near the forward and free ends of the upper portion of the crane or bracing R is a perforation, r, through which one end of a coil-spring, U, is secured, the other end of the coil spring being secured around a screw, U secured about midway and upon one side ofthe arm K, thus forming a spring connection between the bracing It near one of its outer and forward ends and the arm K.

A round the lower ends of the stems a, which are seat-ed in the socketed upper ends of the stocks I and P, are annular grooves u', within which bear the points of adjusting/screws at, which pass through perforations a in the up per ends of the tool holders or stocks l and 1?', said screws serving to release from or rctain secured in place the tool holders or stocks to the free or forward ends of the crane or bracing R.

To the lower ends of the stocks l and Il. is adj ustabl y secured the tracer and graver tools Q and Q', respectively, by means of screwt-hreads cut upon the lower ends of the tool holders or stocks and screw-threads cut upon the inner surfaces of the nuts or thimbles Z', which hold the upper ends of the tools Q and Q in sockets QF in the lower ends of the stocks or tootholders P and l. Thus by this connection it will be readily seen that the tools can he secured and retained within the stocks, and when necessary can he released therefrom by unscrewing them as occasion may require, as clearly shown in Fig. 3 of the drawings.

Projectingr downwardly near the rear end of the long arm K, and secured to its under side, is a lug, V, which has in its lower end a perforation, r, and through the vertical projecting portion of the angular arm O is another perforation, o', and upon the upper side of the angular arm O, near its forward or free end, is secured another and shorter upwardly-projecting lug, Vif, having in its upper end a perl'oration, w, these perforations in the lugs V and XV andthe angular arm O being in aligument with each other. Through these perforations is passed and loosely held, so as to turn, an upper horizontal shaft, X, having secured te cach end of it beveled pinions X and X. The beveled pinion X, meshing with a bevel gear-wheel, X", secured to the upper ends of the stock or tool holder and the bevel pinion X2, meshing with the bevel pinion X', secured to the upper end of a a vertical shaft, Y, the upper end of which is projected through a perforation, m, in a lug, X", secured to the upper part and upon one side, of the arm M. The lower end of this vertical shaft Y passes through a perforation, y, in a lug, Y,seeured to the lower end of the vertical arm M and in alignment with the lng X, and has secured to its lower end a bevel-pinion, Y, which meshes with a bevelpinion, Y, upon the end of another lower horizontal shaft, Z, which is passed through a. perforation, y', in a vertical lug, Y, secured to the upper side of the horizontal arm N. Near the outer or free end of this horizontal arm N, and secured to the upper part thereof', is another vertical lug, Z, having in it a perforation, e', through which is also passed the horizontal shaft Z', and upon this end of the shaft is secured another bcvetpinion, Ziwhich meshes with a bevel gearwlieel, Z, secured to the tracer-stock ll.

The point ofthe graver is hollowed out upon one side, or dcscribesa curve similar to thatol' the ordinary writing-pen, which is its cutting point lfor cutting out the letters, designs, ttc., upon metallic surfaces, and adjustably secured to the graver,a little above its point,is a turnbutton or handheld, c', by which the auxiliary frame and its attached tools are operated.

lheoperative auxiliary frame, with its vari ous attachments, is pivotally and adjnsl'ably secured to the main frame A A A?, l) D, and F F by means of a main zuljustingscrew, B, and the balland-socketjoint previously referred to, (sec Figs. l and 4.of the drawings,) which form the fulerum upon which the anxiliary frame articulates and derives ils universal movements while engraving and tracmg.

Referring again to the angular plates ll', which are secured tothe downwardly-proiecting stems H, it will be seen that about midway their lengths are uj'iwardly -projecting stems Il, which have perlorations IL" therein, th rough which are passed thumb-screws 11, by means of which the work-holding plates H are adjusted upon the plates Hf and held thereon at any desired point; or said tl1u1nl)screws re lease them from the plates 11? when it is neces sary to remove them. These plates lll' and l1 have four or more different adjustments relatively to the tracing and graving tools by means of the thumb or set screws il, pins (l, thumb or set screws c c, and thetelescopic exteusiolrarms l? F.

Within the plates lf ll2 are followers or clampingframes composed of two longitudinal bars, ll lll, and two shorter bars, llf which are placed at right angles tothe former, the ends of the former overlapping them. These bars have perforations I) b b2 tl" therein near each of their ends, through which are passed tlm mbvserews C (1 C3 C', the purpose of which is to hold down in place within the IIC plates or workholders H H'2 the metallic plates or metal surfaces to be operated upon, as clearly shown in Fig. 2 of the drawings.

The operation of my machine will be obvious from the foregoing description ,when taken in connection with the accompanying drawings, but may be briefly rehearsed, as follows: The operatorhaving placed his inet-allie plates or other articles having metallic surfaces in the work-holders to be operated upon, then grasps hold of the hand-hold or turn-button secured to the tracing-tool, by which he traces out the letters or designs of any given size on the surface of the tracing-plate. The auxiliary or operating frame at the same time the tracing or marking out of the letters by the tracing-tool is in progress accommodates itself to every movement made by the traeingtoohand simultaneously with this movement ofthe traeingtool and auxiliary frame a corresponding movement is given or imparted to the graver, which is in alignment with and above the tracing-tool, through the medium of the gearing and their respective shafts, the graver cutting out the letters or designs as traced by the tracer with accuracy and uniformity characteristic of this class of machines. Vhen it is deemed necessary to regulate or adjust the depth of the cut ofthe graver so that a deeper or shallower eut may be given upon the metallic plates or surfaces, the main adjustingscrew is turned to the right, which lowers the operative auxiliary tool-carrying frame gradually, which gives a deeper cut to the tools. On the other hand, if a shallower eut of the tools is desired, a reverse movement of the main screw is given ,whieh raises theauXiliary frame and the tools give a shallower cut. This vertical adjustment which is given to the auxiliary frame and tools relatively to the plate or work holders is attained by another means of adjustmentrelatively to the tools. Instead of adjusting thetool-carrying auxiliary frame, the vertical adjustable arms, which are adj nstably secured to the main frame and which carry the telescopic extension-arms and workholding plates, ean be adjusted upwardly or downwardlyin a vertical direction and injuxtapositiou to the point of the tools by means of the thumb-screws, which loosely hold the arms to the standard of the main frame. Thus it will be seen that the auxiliary frame carrying the tools can be adjusted to the plateholders, and vice versa. A horizontal adjustment of the work or plate holders is also obtained relatively to the points of the tools to any degree desired in a forward and rearward direction by means of the telescopic extension arms telcscopiug in the vertical adjustable horizontal arms and the thumbscrews passing through the perforations in the eollared or free ends of said vertical adjustable arms. Another adjustment can be given the plate or work holders by the same meansi. e., the telescopic extensionarms andthe thumb-screws ot' the vertical adjustable arms-and that is this: the plate or work holders can be adjusted at right angles to the forwardly and rearwardly horizontal adjustment by the lateral movement of the telescopic arms within the horizontal vertical adjustable arms, which gives the plateholders a lateral and angular adjustment of about forty-tive degrees to either one side or the other of the telescopic extension-arms, as desired, the set-screws, which are passed in the perforations in thel free ends of the telescopic arms, serving to steady and keep in proper position the plate-holders, the ends of said screws abutting against the stems of the plate-holders. There is still another and final angular adjustment of the plate or work holders with respect to the points of the tools in a forward and rearward direction, which is done through the medium of the pin which pivotally secures the downwardly-projeeting stems of the plate-holders in the bifurcations in the outer or free ends of the telescopic extension-arms.

The various adjustments of the plate-holding arms and plate-holders are clearly shown in dotted lines in the figures of the drawings.

Other objects of the various adjustments than those herein set forth will be obvious, and further mention of the same are deemed unnecessary.

My machine is simple in its construction, durable, and easily operated.

What I claim is- 1. In an engraving-machine, the combination, with a vertical standard and an upper and lower outer horizontal arm, of the vertically-adjustable horizontal arms, horizontal adjustable telescopic extensionar ms provided with bifurcations in, their outer ends, which receive the downwardly-projecting stems of the plate or work holders, said plate or work holders being pivotally secured to the stems, whereby an angular adj ust-ment is given them, substantially as described.
